Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…

The GALAH survey: Improving chemical abundances using star clusters
Janez Kos, Sven Buder, Kevin L. Beeson +18
Large spectroscopic surveys aim to consistently compute stellar parameters of very diverse stars while minimizing systematic errors. We explore the use of stellar clusters as bench…

On the origin of the Hercules group: I. chemical signatures indicating the outer bar origin
Yusen Li, Kenneth Freeman, Helmut Jerjen +3
The Hercules kinematic group is a kinematic anomaly of stars observed in the solar neighbourhood (SNd). In this series of papers, we present a comprehensive study of this structure…
